(for a 12v outlet) on the end. The housing itself is then enclosed by a
removeable piece of red glass. I suppose it could be intended for use as a
cockpit light that won't harm night vision but the output seems far too low
for it be effective although the length of cable is about right to cover the
distance from power outlets at the nav station to the instrument binnacle in
the cockpit.

Sounds like a cockpit light that won't harm night vision to me. Have you
actually tried it at night to see how much light it emits? If you're
using your night vision then it's not going to have to produce very much
light to be useful. Even if it doesn't flood the cockpit with red light,
it could probably illuminate a chart held next to it, and that might be
all you need.

Could be the outer cover for a binnacle mounted compass. I have a very
similar bit after having to replace the compass capsule on my boat.
Mine has two red LEDs that illuminate the compass very well.

That was my guess also, some sort of compass lighting.

Pete,
I've not tried it in situ as to date I've not been out and about on a dark
enough night away from the city lights but I suspect you are correct. With
no other light in the cockpit it may indeed be sufficient to read any unlit
instruments, compass or chart.
Regards
Andrew

ps - to everyone else who threw in their twopennyth worth , thank you.

how about an aircraft cockpit light. they usually have coiled cables
and a collet that
changes the light from white to red. usually for a 24 volt system
hence half the lumens at
twelve. maybe an inexpensive varity?

Hmmm..inexpensive and aircraft equipment are not words I expect to see
in one sentence usually!
